VENTILATING DEVICE Filed Sept. 24, 1949 INVENTOR H. meson Patented Dec. 25, 1951 UNITED STATES PATENT OFFICE VENTILATIN G DEVICE Herbert Gibson, Toronto, Ontario, Canada Application September 24, 1949, Serial No. 117,685 In Canada October 20, 1948 2 Claims.

This invention relates to a new article oi manufacture which, in conjunction with a previously prepared roof ridge, forms a ventilating means.

It is common to provide ventilating means on roof ridges for ventilation of the building or rooms under the same. Previous devices known to the inventor have possessed the disadvantages that they are formed from a large number of component parts and are therefore unduly complicated and expensive to manufacture. Furthermore, previous ridge ventilating devices known to the inventor are not adaptable for use in conjunction with roof ridges having varying ridge angles.

It is therefore the object of the present invention to provide an article of manufacture which may be used in conjunction with roofs having widely varying ridge angles to form an effective ventilating means, and which is simple in structure, lending itself to economy of manufacture.

With these and other objects in view my invention generally comprises a new article of manufacture having a generally rectangular body portion of sheet metal with end walls formed integrally therewith, flanges extending from said end walls substantially at right angles thereto, and screen members forming side walls for said body portion. The flanges and end walls may be cut, the body portion bent, and the article fixed in simple manner over a previously prepared portion of a roof," to form an effective ventilating means.

In the drawings which illustrate one embodiment of the invention;

Figure 1 is a perspective view of my new article of manufacture, showing the form in which the article is sold.

Figure 2 is a partial perspective view illustrating how the article is cut and bent in order to install it on a roof in the area of the ridge.

Figure 3 is a cross-sectional view showing the article installed on the roof of a house.

Figure 4 is a" partial section on the line 4-4 of Figure 1, showing the manner in which the screen members are attached to the body portion.

Reference numeral Ill generally indicates a body portion of sheet metal having a rectangular top II and end walls I2 formed integrally therewith. Flanges I3 extend from end Walls I2 substantially at right angles thereto. Screen members I4 form side walls for body portion III.

Screen members I4 are preferably arranged parallel to, but inwardly recessed from, the longitudinal edges I5 of rectangular top II, in order to prevent rain, snow and the like from. passing through the screens. Screen members I4, as best seen in Figure 4, are held in place by folding over the end of rectangular top II and crimping the top of the screen member I4 in the thus formed to d.

Two cuts I6 are made along the longitudinal axis of the article through both flanges I3 and end walls I2, but not through rectangular top II. Rectangular portion I I is bendable along the line I 1 which joins the two cuts I6.

The ventilating device of my invention is installed on a roof in the following manner. Portions of flanges I3 are cut away on each side of cut I 6 as shown at I8 in Figure 2. Portions of end walls I2 are then cut away oneach side of cut I6 as shown at I9 in Figure 2. The extent of cutting will depend upon the pitch of the roof ridge upon which the device is to be applied. Cuts are taken which permit rectangular top II to be bent along the line H and strike an angle similar to that of the roof ridge.

The roof ridge itself is prepared for the installation of the device as follows. Between two adjoining rafters 20, a cut 2| is made on each side of the ridge board 22, through the roofing boards 23 and the shingles 25. The device of my invention, cut and bent in a suitable manner, is then placed over the prepared portion of the ridge, and nailed in place by nailing through the flanges I3 into the roofingboards 23. To prevent seepage of moisture under the flanges I3 I prefer to place some shingles 25 so as to cover the flanges I3, (as shown in Figure 3).

Modifications of the embodiment described and illustrated will be apparent to those skilled in building, roofing and carpentry arts. It is therefore intended that the invention should be limited only by scope of the sub-joined claims.

What I claim as my invention is:

l. A ventilating device comprising: a body portion of thin sheet metal having a rectangular top and end walls formed integrally therewith, flanges extending from said end walls at substantially right angles thereto, each of said flanges being formed with a transverse cut extending from its free edge to its edge that meets its related end wall, each of said end walls being formed with a cut that extends from the termination of said aforementioned cut in its related flange thereacross to its edge that meets said top, all of said aforementioned cuts being in a common plane with the longitudinal axis of said rectangular top whereby said top can be folded-about its longitudinal axis to form a. housing-ioij' a venti 3 lator capable of being fitted over the peak of a Number roof. 1,124,875 2.
